Passes 4261–4268
Eight finite-model closures: girth-18 voltage cover, dynamically corrected geometric CZ, full-coordinate Davies metastability, exact 37-auxiliary three-local clock, non-Gaussian Hawking-channel search, Levi quantum search, a rank-one defect bound mode, and two-stage thermal point–line entanglement death.
Highlights
- Girth ≥18: a frozen Z750019 cover passes collision-free radius-8 balls above all 80 base vertices. It is explicit but not compact: 60,001,520 vertices.
- Corrected CZ: four latitude loops give phase −π cos δ, cancel repeatable static dynamical phase by echo, and admit exact transitionless driving with HCD=(n×ṅ)·σ/2.
- Full-coordinate open system: K=20 Davies gap 1.8722329×10−11 in the frozen dimensionless calibration.
- Clock: qutrit Gray digits eliminate the eight dynamic flags, reducing auxiliaries from 45 to 37 while keeping exact 3-locality and the 49-state history.
- Hawking channel: no positive coherent information was found in the audited low-Fock non-Gaussian families for the two τ>1/2 disorder samples; unrestricted capacity remains open.
Outside box
- Exact five-shell marked-vertex search reaches probability 0.7301604209.
- A V=4 onsite defect creates an eigenmode at E=4.9600853314 with 76.2018% defect weight.
- Point–line harmonic entanglement dies in two stages at T=0.9947196822 and T=1.2027283476.
Evidence boundary: these are exact or numerically frozen finite graph/control/open-system statements. They are not fabricated hardware, observed Hawking radiation, a physical spacetime-memory model, a speed-of-light derivation, gravity, cosmology, or a theory of everything.
